Problems solved by technology

All these systems have the drawback of being of low efficiency and make poor use of the input torque, and also are limited to the torque to be transmitted and do not permit the torque to amplified to a sufficient degree.

Embodiment Construction

The proposed invention of a continuous torque regulator consists of a mechanism based on a series of epicycloid gears. An epicycloid gear mechanism is formed by a pinion termed planetary gear which engages with two or three pinions arranged on its circumference, which are given the name of satellite pinions. The driving shafts of the satellite pinions are joined to each other through a frame in such a manner that the relative position is maintained of the three satellite pinions. These satellite pinions are located inside a crown wheel which, toothed on the inside, engages with these satellite pinions.

The continuous torque regulator assembly is formed by three epicycloid gears in which the first and second epicycloid gears are tied by means of a frame which joins the shafts of the satellite gears of the epicycloid gears. The third gear likewise has a planetary gear, but which in this case is joined to the planetary gear of the second epicycloid gear. This third gear also has satelli...

Abstract

Continuous torque regulator formed by a transmission system and a regulating circuit, wherein the transmission system is formed by three epicycloid gears, in which each one is formed by a planetary gear, a series of satellite pinions and a crown wheel, wherein the second and third planetary gears are rigidly joined, and the satellite gears of the third train are double, the regulating circuit having a pressure pump (Bp) which is joined by means of a pinion to the crown wheel (C1), a control valve (Vc) which is joined by means of a pinion to the shaft of the planetary gear (A1) and a valve (N) which in the event of being actuated torque transmission ceases, the assembly permitting the regulation of torque in a continuous form without steps and without any need for interruption mechanisms, it being possible to interrupt the transmission at will.

Description

OBJECT OF THE INVENTIONThe object of the invention proposed herein refers to a continuous torque regulator which is an assembly of mechanisms the purpose of which is to implement a regulation of the torque in a continuous manner, that is without jumps or steps, in other words it is not discrete in form, wherein said regulation is implemented between two values, between zero torque and calculated maximum torque.Among the applications for continuous torque regulators is that of replacing clutches and gearboxes in transport vehicles like motor cars and trucks, being applicable in the machinery of heavy vehicles like tractors, civil works machinery like cranes and excavators, and in all those machines in which the torque to be applied has to be matched to an end job to be carried out. It is of special interest for those cases where the torque is applied in a manner that is not constant but variable and has to be applied in a form that is continuous and without steps.Thus the present inv...
